"Answering machine message 104" joke

"Muppet Show" theme:
It's time to leave a message
After you hear the tone,
It's time to leave a message
' Cause we're not at home tonight...
It's time to leave a message
On Kate and Shannon's phone,
It's time to leave a message
' Cause we're not at home tonight.
Just leave your name and number,
Such simple things to do,
And then when we get home we will
Get right back to you.
It's time to leave a message
After you hear the tone.
It's time to leave a message
' Cause we're not at home tonight.
Gone to get a bite,
Stayin' out all night,
Yes we have a life!
Leave a message, we're not home toniiiiight...
